A crevasse is a deep crack that forms in a glacier or ice sheet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces.
A common form of crevice failure occurs due to stress corrosion cracking, where a crack or cracks develop from the base of the crevice where the stress concentration is greatest. This was the root cause of the fall of the Silver Bridge over the Ohio River , in 1967 in West Virginia , where a single critical crack only about 3 mm long suddenly ...

Scientists are torn about why a massive crack in the earth suddenly appeared outside Nairobi, Kenya.
A crevice is a fracture or fissure in rock. Crevice may also refer to: Crevice corrosion, occurs in spaces to which the access of corrosion-resistant fluid is limited; Crevice kelpfish (Gibbonsia montereyensis), a species of subtropical clinid; Crevice Spiny Lizard (Sceloporus poinsettii), a small, typically shy, phrynosomatid lizard
The shear crack, shown in blue, propagates when tensile cracks, shown in red, grow perpendicular to the direction of the least principal stresses. The tensile cracks propagate a short distance then become stable, allowing the shear crack to propagate. [5] This type of crack propagation should only be considered an example.
